TROUBLE: Stock H/U not recognizing Sub amp
I installed my sub amp this weekend, but the stock HU is not recognizing it with the RCA's plugged into the "SW" jack on the back of the HU. I go the the SW control in the menu on the HU and it says "SW NOT AVAILABLE".
I moved the RCA's to the "R" on the back of the HU and the amp works fine. I plug them back into the "W" and the amp doesn't work.
I tried changing the SSP to "FLAT" thinking that would work, but still nothing.
